Application filed February 14, 1921. Serial No. 444,894.

To all whom it may concern:

Be it known that we, CHARLES F. SMITH and ALoNzo A. WARNER, citizens ofthe United States, and residents of New Britain,

county of Hartford, State of Connecticut,

have invented certain new and useful Improvements in a Guard, of whichthe following is a specification.

This invention relates to guards such, for

)0 instance, as are applied to reflectors of electric heaters, and hasas its object to provide a device of this sort having various featuresof novelty and advantage and which is particularly characterized by itssimplicity and cheapness in construction and its pleasing appearance.

In the accompanying drawing, wherein is illustrated one embodiment whichthe present invention may take:

Fig 1. is a front view of a guard,

Fig. 2 is a partial view thereof in central section, and

Fig. 3 is an edge View, partly in section, of the members to which theguard wires are secured.

Referring to the drawings in detail, it will be seen that the guard hasa plurality of similarly shaped wire petals or loops a secured to andradiating from a center piece 5, and provided at their outer free endswith hooks 0 adapted to catch over the ed e of the reflector d.

ach of the petals is formed of a single piece of wire bent back uponitself to form a pair of arms 10 connected at their outer ends by across portion 11 from the center of which extends a double strandedtongue bent to form the hook c. The arms 10 preferably diverge towardstheir outer ends and the cross portion is curved or bowed, as

shown. The petals are curved longitudinally in a direction at rightangles to the Width thereof, as shown in Fig. 2, so that the guard isgenerally of convex form.

44! The free ends of the wires forming the petals may be secured at thecentral portion of the guard in any suitable manner. However, thesecuring means, shown particularly in Figs. 2 and 3 of the drawings, may

be employed to advantage for this purpose. From these figures, it willbe seen that the center piece 1), preferably formed of sheetmetal, has acylindrical sleeve portion 13. 14: is a ring adapted to fit over thesleeve 13 and having spaced openings 15 and a circumferential flangeprovided with notches 17 corresponding to the openings 15. The ends ofthe guard wires, which are bent u as at 18, extend through the notches17 and into the openings 15. The ring is secured to the center piece byexpanding the outer end of the sleeve as indicated at 19.

Preferably, the open end of the reflector to which the guard is appliedis of slightly greater diameter than the distance between diametricallydisposed hooks c of the guard. Thus, when the guard is applied to thereflector with the hooks c catching over the edge of the latter, thestrains set up in the guard will hold it in place. If desired, the guardmay be held against rotation on the reflector by projections on thelatter. In the present instance, the edge of the reflector is shown asscalloped and the hooks catch in between these scallops. It is, ofcourse, uderstood that the reflector is shown by way of illustrationonly as our improved guard may be applied to other types. 7

It is, of course, obvious that the invention is susceptible of variousmodifications and changes which are within the spirit of the inventionwithout departing from the scope of the following claims, it beingunderstood that the present disclosure of the invention is by way ofillustration only and it is not to be taken as restrictive of ourconception.

We claim:

1. A guard for heaters of the reflector type, comprising a center piece,and a plurality of petals radh ting from the center piece, each petalcomprising a pair of diverging spring arms bent toward each other andconnected together at their outer ends and bent thereat to provide areinforced hook for engagement over the edge of a reflector, and meanson the center piece engaging the inner ends of the stale to hold thesame in opposition to t e hooks for yieldingly binding the latter by thespringi- Wires passing through said notches with ness of said arms onthe reflector. their bent up ends positioned in said open- 2. In aguard, a plurality of radiating ings, and a center piece provided witha. 10 guard wires each having its inner end bent sleeve passing throughand having its outer 5 up, a ring having spaced openings and a cirn flnged ver said ring.

cumferential flange rovided with notches CHARLES F. SMITH. correspondingto said openings, said guard ALONZO A. WARNER.
